Circular Birefringence Refractometer: Method And Apparatus For Measuring Optical Activity - A system and method for detection and measurement of circular birefringences in materials, such as optically active (chiral) liquids and materials that exhibit the Faraday effect. The method and apparatus permit the detection of optical activities via the difference in the directions of propagation the left- and the right-circularly polarized light (components). A beam of light is directed at an interface formed by the optically active medium and another medium such that a difference in the angles of refraction and/or reflection and/or diffraction between the left- and the right-circularly polarized components of the light beam can be detected. The difference in the propagation directions between the two circularly polarized light components is measured on a position sensitive detector and/or is detected as an intensity difference. The circular birefringence in isotropic liquids is a measure of their optical purity (enantiomeric excess) and hence the invention presents a method and apparatus to measure chirality. The invention is thus related to optical rotation (polarimetric) measurements, but has the advantage that it does not depend on path-length traversed through the sample.

Skin Permeation Device for Analyte Sensing or Transdermal Drug Delivery - Devices, systems, kits and methods for increasing the skin's permeability controlled by measured skin electrical parameter are described herein. They may be used for transdermal drug delivery and/or analyte extraction or measurement. The controlled abrasion device contains (i) a hand piece, (ii) an abrasive tip, (iii) a feedback control mechanism, (iv) two or more electrodes, and (v) an electrical motor. Preferably the feedback control mechanism is an internal feedback control mechanism. In this embodiment, the abrasive tip contains two electrodes, i.e. both the source electrode and the return electrode. In another embodiment, the feedback control mechanism is an external feedback control. In the preferred embodiment for external feedback control, the device contains a co-axial or concentric arrangement of the two electrodes. In this embodiment, the abrasive tip contains the source electrode and the return electrode is located at the proximal end of the hand piece. The abrasive tip can be made of any material with a surface that can abrade skin. The material can be conductive or non-conductive. The controlled abrasion device may be provided in a kit, where the kit contains the device, one or more abrasive tips, optionally with a wetting fluid. The method for increasing the skin's permeability requires applying the controlled abrasion device to a portion of the skin's surface for a short period of time. The desired level of skin impedance, and thus the resulting permeability of the treated site, can be set at a predetermined value. Alternatively, the level of skin impedance can be selected based on the desired level of skin integrity, the subject's sensation of discomfort, or the duration of the application. The device contains a control mechanism which uses an appropriate algorithm or signal processing on the conductivity information provided by the electrodes to determine when the desired level of skin permeability has been reached. Once the desired level has been reached, the abrasion device is removed and either a drug delivery composition or device or an analyte sensor is applied to the treated site.

CLIENT-ADJUSTABLE WINDOW SIZE FOR CONNECTIONLESS TRANSFER PROTOCOLS - Described herein are various principles for operating transfer protocols using adaptive flow control techniques. In accordance with some of these principles, a client may adaptively negotiate with a server regarding a window size to use when communicating datagrams using a connectionless content unit transfer protocol like the Trivial File Transfer Protocol (TFTP). In some implementations, a client may inform a server whether to increase or decrease a window size. In these implementations, the client may increase the window size upon determining that a previous window size has led to successful transfer of content without any loss of datagrams and the client may decrease the window size upon detecting a loss of a datagram. Because of the limited resources available in some environments in which these techniques may be used, in some implementations a window size may be increased by small amounts but may be decreased drastically upon detecting a loss.

SHARED BUFFER FOR CONNECTIONLESS TRANSFER PROTOCOLS - Described herein are various principles for operating a connectionless content unit transfer protocol to transmit content of a content unit to multiple clients using a shared buffer. A server may transfer content of one or more content units to each of multiple clients upon request from the client using individual buffers. For each content unit being transferred, the server may maintain a count of the aggregate size of buffers for transferring content of that content unit. If the server determines that the aggregate size of the buffers transmitting a particular content unit is larger than the content unit itself, the server may establish a shared buffer for transferring that content unit to clients. A server using a shared buffer in this manner may transfer content of the content unit to clients using the shared buffer until all requesting clients have received the content unit.

RE-FACTORING, RATIONALIZING AND PRIORITIZING A SERVICE MODEL AND ASSESSING SERVICE EXPOSURE IN THE SERVICE MODEL - The method of the present invention to re-factor, rationalize, and prioritize a service model and to assess service exposure in the service model is illustrated. To be dedicated to every client's success means, in this context, to be sure we are building the right service portfolio for the client that has the highest relevance to what they do, what their objectives are, and what they aspire to achieve. Therefore, we need to periodically pause and review the service model as it stands, infant or mature, and validate its relevance from a client's perspective. This process is called rationalizing the service model (or portfolio). This review can lead to changes (called re-factoring) in the service model due to a re-prioritization. Some services will become more important, others will sink in priority. Thus, the method of the present invention is called service re-factoring and rationalization (SRR). The service model is reviewed and re-factored and the service portfolio and service hierarchy are refined, exposure decisions are made, and finally the service model and its constituent parts are rationalized based on the re-factoring and exposure decisions. Another technique called Service Litmus Tests (SLTs) is leveraged during service re-factoring and rationalization. SLTs are set of gating criteria to select and filter a set of (candidate) services from the service portfolio for exposure. A Service Exposure Assessment Toolkit (SEAT) is also presented in the present invention. SEAT is a mathematical model to facilitate making exposure decisions for services and prioritizing the services in the service model.

METHOD OF TREATING FLUID CONTAINING VAPOR PHASE METALS, VAPOR PHASE METAL COMPOUNDS, OR BOTH - Perlite, particularly, perlite in powdered form, is employed to adsorb metals and metal compounds from fluids, in particular gases at elevated temperature. In select embodiments, powdered perlite is treated to expand its surface area and injected into a fluid stream, such as flue gas, held for a specific retention period, and removed for subsequent disposal. In other embodiments powdered perlite is provided in an adsorption bed. Fluid containing metals or metal compounds in vapor form is permitted to pass through the adsorption bed until the expanded perlite powder is saturated (exhausted) with the metal and metal compounds adsorbed thereon. The perlite is then replaced, disposing of the exhausted perlite. Treatment of perlite by boiling with sulfuric acid or suspending in a suspension of sulfur in carbon disulfide has been shown to significantly expand the surface area of perlite, thus increasing the efficiency of the process.
